MACHINE FOR CUTTING SOLES FOR BOOTS AND SHOES.

Specication of Letters Patent No. 23,516, dated April 5, 15559.4

To all whom t may concern:

Be it known that- I, ALBERT WARREN, of Jefferson, in the county ofAshtabula and State of Ohio, have invented a new and useful Improvementin Machinery for Cutting Soles for Boots and Shoes or Envelops of AnyRequired Size or Shape; and I do hereby declare that the following is afull, clear, and exact description of the construction and operation ofthe same, reference be ing had to the annexed drawings, in which thewhole is exhibited, consisting of a long shallow box, the bottom coveredwith sheet i'ron, and a press working with the foot.

A, A, A, A, are the outer pieces or frame of the box. On the bottom areplaced a series of pieces of wood B, and C, with a crooked edge, alongwhich is a knife (l) of elastic steel. crooked edges and the two piecesB, and O, are tacked together with a small piece of leather bringing theelastic knife snug within the crooked edges of the pieces B, and C, andthus the bottoni of the box covered with two pieces B, and C, and knifeI, between them. In each of the pieces B, and O, are holes marked (F) inwhich are placed spiral springs and on these are laid pieces of thinhard wood in the shape of soles D, D, D, &c, These pieces are placedbetween the knives, I. By placing small blocks between the straightedges of C, and C, they may be greatly widened to out large soles orbeing close together they are much smaller. Different sizes may also beused to cut any required size. E, is a block against which the fourscrews G, G, Gr, G, work and which being screwed, brings the wholecompletely together.

H, is a projection of the bottom.

By placing each pair of pieces as B, and C, with a knife (I) betweenthem, so as to cover the bottom in the manner represented in thedrawing, that is, alternately, first with the toe to the left then a toeto the right, it will be seen that the soles cut will This knife is bentto tit these be alternately right and left soles, or each knife cuts onone side a right sole and on the other side (being turned) a left sole,with perfect accuracy and at the same time with the greatest economy ofmaterial.

In operation, which is with a press working with the foot (shown in aseparate drawing) as you shore in and cut the several soles the forms D,D, D, &c., are thrown up by the springs (F) and with them the cut solesat the top and withdrawing the box the slide upon the press scrapes thecut soles all ofi' together.

The press I use is shown in another drawing` and is worked by the foot.

L, is the lever, worked by the foot.

M, is the upper beam.

N, is a block which coming upon the leather presses it upon the knivesand cuts the soles.

O, a cleatupon the beam.

P, is a slide working freely in two mortises in the cleat O, and bearingits weight upon the box and when all the soles are cut (as they arealternately as the box is shoved in) on withdrawing the box the cutsoles are scraped off together as before stated by the slide P.

That I claim as my invention and desire to secure by Letters Patent is-A series of pieces covering the bottom of the box .like C, C, separatedby a straight line through the center; together with the series ofpieces like B, O, with the knife I, held securely between their crookededges and arranged alternately with a toe to the right and left andcovered by the forms D, D, D, &c., in the manner described; when thesedevices are combined with the slide l), arranged and operating as hereinbefore specified.

ALBERT TAB-REN.
